F R. LONG COUPLING NUT Fie July 30, 1936 Patented jan. 12, 1937 J namanSTATES P-ATENT oFrcE mlzw N constructed as to become easily broken whensubjected to a hammer blow in either driving the coupling nut home orreleasing it to separate the union.

.Acordingly, a primary object of the present invention is tovprovide acoupling ring or socalled lug nut having a substantial body portionformed exteriorly with a plurality of angularly related faces for aportion of the depth thereof while the remainder of such depth is formedwith radially projecting lugs of special formation. These lugs projectsufficiently beyond the maximum diameter of the body to afford properanvil faces andalso adequate leverage not only to convert a hammer blowor the like into rotary motion but also to distribute the force of theblow to opposite sides of the body to avoid breakage of they lugs. i

A further object of the invention is to provide a lug nut or couplingwhich may also function as a pipe hanger when used in connection with asupport.

With the above and other objects in -view which will more readily appearas the nature of the invention is better understood, the' same consistsin the novel construction, combination, and arrangement of partshereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in theaccompanying drawing in whichz- Fig. 1 is a perspective viewillustrating the application of the invention.

Fig. 2'is a side-elevation of the present improvement.

Fig. 3 is a top plan View of the invention installed for use, portionsof the same being broken away to more completely illustrate the mode ofIn the embodiment of the invention shown in the accompanying drawing thesame includes in its organization a body designated generally as- I,which is of annular formation having an internally threaded portion 2for engaging with the 5 threads 3 of one portion of a pipe couplng andthe interior annular shoulder 4 for engaging with a rib or shoulder onthe mating part. of the coupling. i

The body is externally provided with a plural- 10 ity of tool engagingportions designated generally as A and B arranged in adjacent relationtransversely of the axis of the body thereby to enable the body to beengaged by either a wrench or a hammer for imparting rotary or turningmove-15 ment thereto.

The tool engaging portion A preferably comprises a plurality of fiatcontiguous angularly related faces 5 which may in effect provide ahexagonal or other form of nut adapted for wrench 2 engagement. The saidfaces 5 are disposed in tangential relation to the annular face 6 of thebody. Adjacent to the said angularly related faces 5 the body isprovided with the tool engaging portion B, namely, the offset wings 1--1which 25 are of substantially triangular formation with the apices 8thereof extending outwardly beyond the body and considerably beyond thefaces 5 as willbe apparent from the drawing. The side edges of thetriangular extensions 'I-'l form anvil faces 9 which diverge inwardlyfrom the apices fiitoward the body so that the anvil faces of oppositetriangular members not only meet as indicated at IO but said faces liesubstantially tangentially to the annular body' portion 6 previouslyreferred to.

From the foregoing it will be apparent that the body of the nut or ringis provided for a portion of its depth along its axis with contiguousangularlyA related faces and for the remainder 40 of its depth isprovided. with the triangular lug extensions. This arrangement makes itpossible for 'a wrench to have free access to the tool engaging portionA without interference from the triangular lugs 1 and also makes itpossible for ,45 a hammer (indicated in dotted lines in Fig, 1) to haveadequate purchase on the anvil faces 9 of the triangular lugs withoutinterference from the wrench engaging portion. Thus, when it is desiredto tap the coupling home it will be apparent that the force of thehammer blow is distributed over substantially 180 degrees of thecircumferenc'e of the annular or ring-like body thereby effectively toimpart the full 'force of the blow to the coupling body without breakingthe lug and at the same time ob e-.vethe full henefit of the hlow incompletely seating the couplne. The triangular lugs 'i are therefore adistinctive 'feature of the invention. Moreover, their location withrelation to the wreneheng'aging portion has the advantage of makingitpossible to use a wrench and hammer simultaneously, if desired.

A further practical advantage of the lugs 'l is that they may provide a.pipe hanger asillustrated-in Figs. and 5. For example, suitable bracketmeans including the arms or pins ii-ii may be secured to a support andthe lugs 'l-l may rest thereon In the example shown the arms or pinsli'-li may be formed from a single U-shaped piece of metal. The supportsmay be placed at the'location of the lugs wherever the union happens tobe located and will eflectively prevent retrozrade movement of the pipeline. The distinctive feature is that the coupllinn has outwardlyextending means for. enge i fa sup--v aoerme I claim:-
